BBC notes that Russia's Federal Migration Service is said to have issued a document, and that he is due to receive it shortly.
On Tuesday his Moscow lawyer, Anatoly Kucherena, said that if Snowden is granted a one-year temporary asylum, the term "can be prolonged for another year and this can be repeated an indefinite number of times afterwards."
“He’s planning to arrange his life here. He plans to get a job," Kucherena, who has links to the country's intelligence service (i.e. FSB), told RT. "And, I think, that all his further decisions will be made considering the situation he found himself in.”
